Why Newton's first law of motion contradict to daily life specially for uniform motion?

Answer 1

Newton's laws of motion are made when thinking that the objects are in a vacuum.

Living on Earth, we have an atmosphere (air).

So the atmosphere will interrupt all the objects tested.

For example, when throwing a ball in space, the ball will continue on forever, because there is nothing to disturb it. Until off course something does disturb it, like a meteor or a black hole.

But throwing a ball here on Earth, it will only fly for a bit. There is the air that will cause friction and make it slow down (even though it is very small) and most important of all, gravity.

newton said that if no external force act upon any moving object than it will move through out.. but in actual world .. there are lot of external forces.. and those are frictional forces.. so newton first law holds..

Answer 2

In daily life, we often perceive motion as requiring a continual application of force to maintain it. However, Newton's first law states that an object will remain in uniform motion (constant velocity) unless acted upon by an external force. This can be counterintuitive because we are used to experiencing friction and other forces that tend to slow down objects in motion.
